UNITED STATES REINHARD GUYOT, OF LOS ANGELES, CALIFORNIA.

TIME STATION INDICATOR.

Application filed July 25, 1928.

This invention relates to devices usedbv streetcar and railroad men to indicate the proper times at which certain stations are to be reached.

One of the objects of this invention is to facilitate a setting of an indicator to show the proper time at which any station is to be reached regardless of the starting time.

Another object is to provide a station-indicating dial adjustable and in relation to the time-indicating dial ot a tlht'll.

Another objectis to provide a reversible station-indicating dial having on one side the stations in an order in which they tollow in one direction, while the same stations appear on the opposite side in the order in which they follow in the opposite direction.

Other objects will appear from the following description and appended claims as well as from the accompanying drawing. in which-- Fig. 1 is a front elevation of a timepiece. with a station-indicating dial surrounding the 'time-indicatng dial of the timepiece to indicate the proper time at which any of the stations is to be reached regardless of the starting time according to this invention.

Fig. 2 is a fragmentary cross section through a casing and adjustable dialwith means whereby the dial can be clinched to the edges of the casing.

Considering that railroads and especially streetcars traverse the same route repeatedly and often many times a day whereby the conductor or operator is held to certain schedules to reach certain points at. a certain time, though trafiic orother conditions frequently interfere either with the beginning or during the run of certain trips, it will be clear that printed schedules are not very satisfactory since a conductor or operator is under existing conditions frequently compelled to figure out his own schedule and only comparatively follow the instructions from his main office.

The principal feature of this invention is therefore to give the conductor or operator a chance to equally adjust or reset his indicator whenever a change in the schedule becomes necessary through tratfic conditions.

As illustrated, a time iece, as for instance a watch, is roughly in icated in the center of the illustration in Fig. 1 at 3.

An annular indicating dial 4 surrounds the dial of the timepiece 3. This annular Serial No. 295.281.

indicating dial is adjustably mounted in relation to the central time dial 3.

if, for instance. a streetcar is supposed to start at five minutes past three from a cer tain point. as for instance the end of a. certain line. the indicating dial 4 is moved around the time dial so that the starting Station indicated at 5 is brought into align ment with the large hand 6 of the timepiece. The indicating dial 4 is maintained in this position in relation to the time dial through out the run of the streetcar to the opposite end of the line.

All different stations commonly used as steps, or the principal crossings, or junctions that such a streetcar is suppose to pass or traverse are provided on the indicating dial, as. for instance, designated by the numerals 7. 8. 9. 10, ll, 12,13 and 14.

Tt then on a certain run such a streetcar is unduly stopped or detained through tratiic conditions, or accidents, or other occurrences beyond the control of the conductor or operator of such a streetcar, the indicating dial may be resetat the next junction or station indicated on the indicating dial.

For instance. if the station 10 according to the'setting illustrated in Fig. 1 should have bcen'rcached at 25 minutes past three, however, this certain streetcar has been de tained 10 minutes, the indicating dial 4 can be moved around so that the station 10 aligns with the central time dial at 25 minutes to four. It will then be apparent that all following stations are automatically again correctly placed so that the hand 6 of the timepiece will move around on the dial of the timepiece to indicate the proper time at which such remaining stations should be reached.

The indicating dial is preferably designed with two diflerent indicating faces on the opposite sides so that one trip may be shown on one face of the indicating dial while the return trip of the same streetcar can be shown on the reverse or back side of the indicating dial.

This indicating dial is, furthermore, preferably designed that it may easily be removed to be turned from the front side to the back side and to be moved around the time dial of the central timepiece.

In Fig. 2 a simple structure is illustrated which allows such a moving around the central timepiece and which allows a reversing from one. side to the other of the indicating dial.

The indicatii'ig dial at is provided with a central opening or aperture indi ated at 15 through which the dial of the timepiece 3 is risible. The edg t-s ot the indicating dial are designed to clinch ever the edges 16 of a casing 17. A. space is provided between the casing 17 and the indicating dial. 4; for the timepiece 3 so that the timepiece may be properly held and aligned centrally below the indicating dial in The clincher rim to is provided with oppositcly disposed clinching edges 19 and 2t). This clincher rim is preferably madcot. yieldingly and suitably elastic material, such as pasteboard or. more preterahly, such as rubber so that the edges 19 and 20 will securely clinch over the edges 16 of the casing 17.

The indicating dial 4 is centrally located between the clinching edges if) and 20. The rings 21 are merely used to 't'orin a more rigid structure so that in case where a return indicating dial 4 is desired and where a comparatively strong and elastic clincher rim '18 is used, the elastic clincher rim does not un- .necessarily press on the edges of the indicating dial 4;, so as to eventually unduly press this indicating dialeut of shape,

The reinforcing rings 21 have a tendency of maintaining the indicating dial 4 in flat and properly annular shape. within the strongly elastic clincher rim 18.

From the above it will be clear that no particular schedule is to be written for cer tain days or certain times of the year. A conductor or operator of a street car can easily set the indicating dial in proper relation to the central time dial according to the instructions of his head otlice and automatically obtain a proper schedule for the various stations along his route.

The head otiice of a street car company under these conditions has onlyto provide a certain number of indicating dials for the different routes, the indicating dials for each route being absolutely alike for the various street cars starting at various times from a certain point of such a route. Having received his starting time for the various runs during the day, a conductor or motorman is easily able to get the various time indications for the various stations along his run by setting the indicating dial to the ditferent starting times in relation to the timepiece of his time-, station-indicator.

Trips on a. certain route, of course,.may extend over an hours time and it must be und rstood that on the same indicating dial a route can easily be indicated for over an hour by using for the second or third hour dili'erent colors. on the other hand, several dials, of course, can he used for the. several hours. This is merely av matter of choice on the part of a railroad or transportationcomparty, or the conductor, or operator of a train and therefore is well within the understanding and teaching given in this application.

Havin thus described my invention, I claim l. A time-, statioi'i-indicahir comprising a centrally disposed t.ime1')iece, a casing in which the timepiece is mounted and which extends with its outer edge beyond the outer contours of the timepiece, and an annular station-italicator having stations indicated on opposite sides and having an engaging rim with resilient engaging edges on opposite sides oi the indicator adapted to hold the indicator with its opposite fiat sides to the edge oi the casing.

2. 111a time, station-indicator, an annular station-indicator made of a flat material with a central aperture around which certain stations are marked on the two opposite flat Faces of the indicator, adapted to engage over the outer edge of the indicator and a clincher ri-m having clincher edges projecting over the two opposite fiat faces of the indicator.

3. In, a time-,.station-indicator. an annular station indicator made of a flat material with a central aperture around which certain stations are marked on the two opposite flat faces of the indicator, adapted to engage over the outer edge of the indicator and a clincher rim having clincher edges projecting over the two 0 posite flat faces of the indicator, and rein orcing rings disposed on the opposite flat sides near the outer edges of the indicator for holding the indicator within the clincher rim.

In testimony that I claim the foregoing as my invention I have signed my name.
